Control system for hydrostatic energy storage type hydraulic transmission type wind turbine generator system

Abstract

The invention discloses a control system for a hydrostatic energy storage type hydraulic transmission type wind turbine generator system. The system comprises an industrial personal computer located in a central control room, a first network interchanger, a main controller, a touch screen located in a cabin, a second network interchanger, a subordinate controller and a cabin control subsystem, a motor room control subsystem is connected to the main controller, the main controller is connected to the industrial personal computer through the first network interchanger, and the cabin control subsystem is connected to the back of the subordinate controller and the touch screen and is connected with the first network interchanger through the second network interchanger; a principal-subordinatedistribution system of an industrial personal computer monitoring cabin control subsystem, a motor room control subsystem and a touch screen monitoring cabin control system is constituted, different controllers arranged in the main control room and the cabin are arranged to cooperate with each other synergistically, and the system not only timely and efficiently controls the cabin and a motor, butalso achieves communications and signal transfer between the two controllers.

Description

technical field [0001] The invention belongs to the technical field of wind power generation control, and in particular relates to a control system for a hydrostatic energy storage type hydraulic transmission type wind power generating set. Background technique [0002] In recent years, the world's wind power industry has developed rapidly and has gradually played an increasingly important role in alleviating energy and environmental crises. [0003] The traditional wind generator mainly adopts the gear box structure, which mainly includes the wind wheel, the main shaft, the gear box, the generator, and the power electronic components. [0004] With the continuous advancement of technology, a hydrostatic energy storage type hydraulic transmission type wind turbine has appeared. The generator in this unit mainly includes a nacelle, a motor and a tower, and specifically includes a wind wheel, a main shaft, a hydraulic pump, High pressure piping, low pressure piping, accumulat...

AI Technical Summary

Problems solved by technology

Compared with the traditional gearbox-type generator, the hydrostatic energy storage hydraulic transmission type wind turbine has many internal subsystems, and different devices are located in different positions. Manual detection and control are required next to each system, so that the static The control of the liquid energy storage type hydraulic transmission type wind turbine is very inconvenient, and the monitoring mechanism of the traditional generator cannot be directly used

[0005] Aiming at the problem that the hydrostatic energy storage type hydraulic transmission type wind turbine cannot be effectively monitored in the prior art, no effective solution has been proposed so far
